WEATHER STRIP AND METHOD OF MAKING THE SAME Filed Feb. 4; 1930 Patented June 7', I932 UNITED STATES PATENT] OFFICE WILFRED A. SMITH, OF AKRON, OHIO, ASSIGNOB. TO THE B. F. GOODRIGH COnPANY,

OF NEW YORK, N. Y A CORPORATION -OF NEW YQRK WEATHER. STR P AND METHOD 0! MAKING THE, SAME This invention relates to weather-stripsand to methods of making the same, and more especially it relates to weather-strips such as are used with the upholstery of closed automobile bodies for obscuring the crevices around the doors thereof, and for closing said crevices a ainst the weather.

Hereto ore weather-strips of the character mentioned have been. made chiefly of rope or rubber tubing, and covered with suitable fabric to match the upholstery of the car, said fabric being so formed and stitched as to provide a radial attaching margin extending longitudinally of the strip, which margin in some cases, is reinforced. Such weatherstrips, when new, lie snugly in, the desired position, but later are. likely to sag and stand away from the underlying crevice whicli they are designed to close, due to the non-resilient character of the material of their attachment portion. 1

The chief objects of this invention are to provide a weather-strip for the purpose men tioned, of which the attaching portion will possess inherent resilience; to provide such a weather-strip having a unitary body portion and attaching portion; to provide a weather-strip havin a unitary body portion composed of di erent materials; and to provide an improved method of making weatherstrips.

Fig. 4 is a sectional view of a mold, and a weather-strip therein in the final stage of manufacture.

Referring to Fig. 1 of the drawing, the Weatherstrip-comprises a generally cylindrical body portion 10, a radially disposed attachment portion 11; and an ornamental fabric cover 12 mounted upon said body por Application filed Iebmary 4, 1.930.. Serial No. 425,800.

tion and extending onto said attachin portion. The body portion 10 prefera 1y is tubular to provide economy of material, and preferably is formed of soft cellular rubber. The attaching portion 11 is composed of resilient material suchas rubber, which for the sake of economymaybe a fibrous rubber composition, and it. extends. into the body structure 10 and is vulcanized thereto to provide a unitary structure. The cover 12 is vulcanized to the bodyportion'lO and attaching portion 11,- and preferably i's'flush with latter as shown. f'

In the-manufacture of the weather-strip, the cellular rubber composition in plastic unvulcanized condition iscalendered or other wise applied to one face of a strip of covermaterial 12. A marginal portion of astrip of attaching material 11 is then adhered to one marginal portion of the coated coverstrip' 12, .on the coated side thereof, as is shown in full lines in Fig." 3,;and then the 'opposite marginal portion of the latter is folded over and adhered to the same marginal portion of the attaching strip 11, on the opposite side thereof, as is shown in broken lines in the same figure. The assembled structure is then vulcanized, preferably in a mold 14, as shown in Fig. 4..

For use, the attaching portion 11 of the weather-strip is secured to a door-frame, such as the door-frame 15, Fig. 2, of aclosed automobile, by tacks or nails 16, the strip .be-- ing so positioned that the cylindrical body portion thereof lies'upon the crevice 17 between the door-frame 15 and the door 18 of place during use, that is, at the juncture of the body portion and attaching portion. I

' My improved method of manufacture makes for economical production, especially in large quantities, since it is readily adaptable to continuous coating,. folding and as- I semblin operations.

Iclaimi 1. A weather-strip comprisin a generally cylindrical-member, 1a fiat resi 'ent member nally thereof and united directly therewith in a unitary structure and an ornamental cover secured to both members.

2. A weather-strip comprising a generally e 0 rubber,

cylindrical member of one gra and a flat resilient member of a different longitudinally thereof and united therewith to provide a unitary structure. a

3. A weather-strip as defined in claim 2 in Y which the cylindrical member comprises soft.

cellular rub a 4. A'weather-strip comprising a enerally cylindrical member com sed o ru ber, and

p a flat, resilient, longitudinally dis osed memher inset in the wall thereof an extending radially therefrom. I

5. A-weather-strip comprising a cylindrical bodfi portion of soft cellular rubber, and

a radia y-disposed, longitudinally extending attaching portion of-denser rubber compos1-- tion vulcanized thereto.

'6. A weather-strip comprising a cylindrical body portion of soft cellular rubber, and

a radiallly-disposed,longitudinally extending attac ing portion of denser ru ber composition inset m said bod portion and vulcanized thereto to provi e a unitary1structure.
